  • Title: Hierarchical self-assembly of nematic colloidal superstructures.
    Author: Skarabot M, Ravnik M, Zumer S, Tkalec U, Poberaj I, Babic D, Musevic I.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2008 Jun; 77(6 Pt 1):061706. PubMed ID: 18643286.
    Abstract:
    We show that colloidal superstructures could be assembled in mixtures of large and small colloidal particles dispersed in a nematic liquid crystal. Using elastic interaction of small colloidal particles with the disclination lines we succeed to demonstrate how one can decorate with small particles a topological matrix of defect rings and loops formed by an array of large colloidal particles. Our simulations show that this concept of colloidal self-assembly in nematics could be extended down to the nanoscale particles.
